appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, tion.

This invention relates to a horn, and more particularly to that class of horns that are rnown as amplifying-horns, these being mainly used on talking-machines and as megaphones. The invention is designed to provide a horn of this class that can be taken apart, the larger end of the horn and the major portion or its length being made of separable sections that will fit one on the other, so as to make a compact package for transportation or storage.

The invention is further designed to pro vide means for holding these separable sections when they are assembled to form the which form a no. t of this speciiicameans on the smaller end of the horn for holding all parts together, so thatthe small and large ends are rigidly and securely connected.

Our invention is illustrated in the accompa nying drawings, in which Figure 1 is a half-elevation and half-section of the horn assembled. Fig.2 is a perspective view of the elements making up the small ends of the horn and two of the separable sections that constitute the large or the flaring end. Fig, 3, is a section of two of the sections of the horn, this view being taken on line 3 in Fig. 1.

As illustrated, our horn is made up, on the larger end, of the sections 10 that are of a configuration that permits of a series of these sections to be put together to make a horn of the desired shape. Each of these sections on one edge has a channel-shaped rib 11 and on the other edge a turned-over TLC rib 11 is soldered 10 but it may be otherwise secured, or it mighi be bent up from the same piece. The rib 12 may be made of any suitableshape, so

norn and a still further object is to provide aportion 12. to one edge ot a section Specification of Iietters Patent.

holding means, however, might be changed,

as long as the structure was devised to hold the ribs on the adjacent edges of the sections 10 together. These sections when thus assembled are prevented from collapsing or from being separated, and in the small end of these joined sections-is 'forced a conical sleeve 16, that has a larger flaring end 18 of Whi ch fits up tight inside the flat inner edges or tongues 10 of the sections 10. Around this joint and havin one edge n engagement with the rib 17 and the other edge in contact with the inner ends of the ribs 11 and 12 is the band 19, that is slipped around the horn, and the ends 20 are drawn together by a set-screw or similar re ulating device 21.

t Willbe seen from this descri tion that the small end of the hornis eas y packed Way-that is, the elements 16 and 19and the larger part of the horn is made up of 'separable sections 10 that are duplicates of one another, and these sections can be folded dr periphei al rib l7, and the laid in a pile, and they take up verylittle room.

The particular kinds of fastening means for the ribs and'a lso for the band 19 can have alternative constructions to perform, their functions Having thus described our invention, What We claim isl. A horn comprising a tapered sleeve at its small end, its large end made u of assembled. sections detachably secure together, each section having a fiat tongue on its inner end, and adetachable band for covering the tongues and clamping them around and against the tapered sleeve.

2. A horn comprising a taoered sleeve, at its small end, a large end mad able sections, each sectionhaving one edge provided opposed edge adapted to be clamped, whereby the adjacent sections are secured together, and means for clamping the assembled sec-' tions on the tapered sleeve. 7 I

3. A horn comprising a tapered'sleeve at its inner end, a large end composed of separable sections, each section having a hollow rib on one edge, and a rib on its other edge to e up of detac enter the hollow rib on the adjacent section,

means on the ribs for fastening the sections together, and means for securing the assembled sections on the large end of the tapered sleeve.

4. In a horn comprising a tapered sleeve at its smaller end, the larger end of the horn being made up of separable sections, each section having a hollow rib on one edge, and having on its other edge a rib to enter the hollow rib on the adjacent section, clips to go over the ribs to fasten them together, the inner ends of the assembled sections fitting on the large end of the tapered sleeve, and means ofMay,1906.

sections, a peri heral 'rib on the tapered sleeve, ribs on t e adjacent edges of the assembled sections, a peri heral band between the rib of the sleeve an the ends of the ribs on the sections, and means for drawing the ends of the bands to ether. I

6.- In a horn ma e up of detachable sections, each section comprising a body portion, a hollow rib on one edge, a rib-on the op posed edge of the section to fit the first-mentioned ri and ivoted clips on the hollow ribs and arrange when in place, to cover the open side of the hollow rib.
